ENTERTAINMENT WEEKLY: How much of the story were you allowed to know before shooting?
MADISON ISEMAN:None of us knew anything.
You’re really watching our characters trying to put this whole thing together just as much as we are.
Is it my favorite way to work?
I’m not kidding, we were all so stumped on set.
All the information is in front of you.
The payoff is really rewarding.
Let’s get into your various roles on the show.
Yes, very much three different characters, and it was complicated.
What went into playing these roles technically?
Did you do anything to help switch your mindset when you had to change characters?
Did you have to listen to a different playlist?
I always thought of them as different pairs of shoes.
When I would put on my Lennon boots, it was a full physical body change.
It was the way she walks in the room and just stands up straight.
She’s the kind of girl who reaches out to people.
Allison is much more reserved and doesn’t like to be touched she’s insecure with her body.
I definitely used a lot of music.
I think I had my headphones in pretty much the whole time.
How did you film that?
We tried it many different ways.
I think in the water, what they ended up going with was a full face replacement.
I think the other body you actually see is my acting double.
That was an interesting day, but it turned out really great.
Is she not dead?
And then to have her body show up, it let the audience know you were doing something different.
And I love that we play into that, because I think that’s what everyone will be expecting.
I think initially, that’s what everyone’s going to think.
Do you have a favorite episode?
Oh, yes, I do.
It’s episode 8, and I literally can’t get into why.
And then it’s all so confusing, and by 8, it finally all makes sense.
It was just the perfect way to wrap up the show.
New episodes ofI Know What You Did Last Summerare available Fridays on Amazon.
